GAS-REGULATOR.

Specification of Letters Patent No. 24,253, dated May 31, 18159.

To all whom it may concern:

Be it known that we, DAVID VHEELER, of Fairfield, in the county of Fairfield and State of Connecticut, and ISAAC LITTLE, of Bridgeport, in the same county and State, have invented a new and useful Improvement in Gas-Regulators; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which drawing a central vertical section of a gasregulator with our improvement applied to it is represented.

A, is a cast iron boX or casing of a form substantially like that of some gas regulators heretofore used, having the inlet a, for the gas at the bottom, and the valve seat Z), directly above such inlet, and the outlet 0, which leads to the burners at the top of a chamber a, at one side of the valve seat. The inverted cup (Z, upon which the pressure of the gas acts to control the opening of the regulating valve 6, is attached directly to the valve stem f, and floats in an annular basin 9, g, of quicksilver, provided in the upper part of the box; said cup being guided by guide-pins h, 72,, which -are at tached to it to work through holes in acap B, which covers said cup and the quicksilver basin.

D, is a diaphragm provided with a suitable number of small openings 2', 71, through which the gas has to pass to act upon the lnverted cup; said diaphragm being for the purpose of preventing the valve belng caused to dance by sudden but trifling fluctuations in the pressure at the inlet of the regulator. The bottom of the chamber 0, is some distance below the valve seat, and we have represented it as provided with a cock E, so applied that by opening it any water or liquid that may drip from the outlet 0, into the chamber 0, might be allowed to escape to the inlet a. This cock is represented as a means of escape for the drip equivalent to some means in use and not self-acting, but requiring to be operated by hand; the object of its representation being to compare it with the inverted siphon S T, which is the subject of our invention and which constitutes a self-acting apparatus for the same purpose.

The siphon S T, has one leg S, screwed into or otherwise connected with the bottom of the chamber 0, as nearly as convenient below the outlet 0, that any drip from the said outlet may fall into it. The other leg T, is open to the atmosphere. The height of this siphon is such that it will contain a column of water or other liquid in each leg of suflicient height to balance the highest pressure of gas, the said water to act as a seal to prevent any escape of gas.

The drip from the outlet pipe dropping into said siphon or running thereinto from the bottom of the chamber 0, is all carried off from the regulator. The leg T, of the siphon, may be made shorter than the leg S, and the water or liquid collected in it be allowed to overflow into a suitable receptacle; but we prefer to have its upper part in the form of a cup, as shown in the drawing, wide enough to contain a large quantity of liquid and fill up very slowly, and this cup may be made to screw on and off, and a cock be provided in the siphon below it to be closed temporarily while the said cup is taken off to be emptied, when 7 DAVID WHEELER.
